I see on the ol' TeeVee, on the science programs, they occasionally have shows on black holes and there they talk about "super-massive black holes."
My question is, Does a super massive black hole have more or less or equal gravitational pull than a normal sized black hole? Does the "super massive" refer to their size only? (measuring many light years across) Can there be limit in the size of black holes? I'm thinking more on the small side. Can there be a black hole the size of a quarter or a basketball hoop? and if so would it be just as strong as a super massive black hole?
Thanks.
